Abstract: A contactless delivery locker may have a locker housing with a locker door fitted to the locker housing. A disinfecting system may be arranged to disinfect the locker content and a remotely actuable lock may be arranged to secure the locker door in a closed position and actuable to release the locker door. A controller associated with the lock may be configured to actuate the lock and a wireless interface may be connected to the controller and configured to receive a command to actuate the lock to release the locker door. The controller may operate to control actuation of the lock to release the locker door upon detection of a command to actuate the lock and release the locker door. The controller may be configured to report lock status information to a user to confirm if a locker has been opened after completion of a disinfecting cycle.

Abstract: A portable operating device for controlling a kitchen appliance from different operating positions having a base body, at least one control element, which is displaceable relative to the base body, for the user to input control information, at least one sensor for detecting a relative movement between the at least one control element and the base body, and a communication unit which is connected to the at least one sensor in a signal-transmitting manner in order to wirelessly transmit, to the kitchen appliance, control information which correlates with the relative movement.

Abstract: A process for the production of a fluorinated quartz glass including the steps of generating SiO2 particles in a synthesis burner; depositing the resulting SiO2 particles into a body; and vitrifying the resulting body, wherein a fluorinating agent having a boiling point greater than or equal to ?10° C. is supplied to the synthesis burner.

Abstract: The invention relates to the production of an anti-resonant hollow-core fiber consisting of a capillary blank and a sleeve tube. The capillary blank comprises an external capillary and a nested internal capillary, and is stretched to a maximum external diameter ODARE_cap and a maximum wall thickness WTARE_caP. The blank is mounted on the inside of the sleeve tube. In order to retain the advantages of the pre-produced capillary blank with respect to ease of assembly and precision, while keeping the associated drawbacks owing to ovality low and predictable, it is proposed that the geometric internal diameter and external diameter of the external capillary and of the internal capillary, as well as ODARE_cap and WTARE_caP, are aligned in relation to one another in such a way that the ARE-external capillary of the capillary blank has a degree of ovality of less than 1.025.

Abstract: Methods are known for producing an anti-resonant hollow-core fiber which has a hollow core extending along a fiber longitudinal axis and an inner jacket region that surrounds the hollow core, said jacket region comprising multiple anti-resonant elements. The known methods have the steps of: providing a cladding tube that has a cladding tube inner bore and a cladding tube longitudinal axis along which a cladding tube wall extends that is delimited by an interior and an exterior; providing a number of tubular anti-resonant element preforms; arranging the anti-resonant element preforms at target positions of the interior of the cladding tube wall, thereby forming a primary preform which has a hollow core region and an inner jacket region; further processing the primary preform in order to form a secondary preform, including an elongation process; and drawing the secondary preform in order to form the hollow-core fiber.

Abstract: The invention relates to microstructured optical fibers that are drawn through hollow channels and have a core region, which extends along a fiber longitudinal axis, and a jacket region surrounding the core region. The aim of the invention is to reduce a damping increase due to corrosion and to reduce the emission of chlorine on the basis of the microstructured optical fibers. This is achieved in that at least some of the hollow channels are delimited by a wall material made of synthetic quartz glass which has a chlorine concentration of less than 300 wt. ppm and oxygen deficiency centers in a concentration of at least 2×1015 cm-3.

Abstract: The invention relates to an anti-resonance ele-ment preform for producing an anti-resonant hollow-core fiber, in an axial top view comprising a circular first cir-cle element with a first circle radius and a circular arc-shaped first circular arc element with a first circular arc radius. Furthermore, the invention relates to a method for producing an anti resonance element preform, a preform for producing an anti-resonant hollow-core fiber comprising at least one anti-resonance element preform and an anti-resonant hol-low-core fiber. According to the invention, it is provided that the first circle element and the first circular arc element are connected to one another at two contact points.

Abstract: A method for controlling a cooking appliance of the basis of a control command transferred from a mobile device to a control device via a wireless data connection, comprising the steps of: capturing a plurality of the sample values correlating to a signal strength of the wireless data connection, determining a test value on the basis of the plurality of sample values, comparing the test value with a reference test value to determine a comparison result, limiting the controllability of said cooking appliance by means of the mobile device according to the comparison result.

Abstract: A contactless delivery locker may have a locker housing with a locker door fitted to the locker housing. A disinfecting system may be arranged to disinfect the locker content and a remotely actuable lock may be arranged to secure the locker door in a closed position and actuable to release the locker door. A controller associated with the lock may be configured to actuate the lock and a wireless interface may be connected to the controller and configured to receive a command to actuate the lock to release the locker door. The controller may operate to control actuation of the lock to release the locker door upon detection of a command to actuate the lock and release the locker door. The controller may be configured to report lock status information to a user to confirm if a locker has been opened after completion of a disinfecting cycle.
